ABSTRACT
Estimated fishing mortality and exploitation values for L. rohita and L. calbasu indicated that their stocks are under heavy fishing pressure. Exploitation values were much higher than the optimum level of 0.5 and remarkably higher than the Emax values. Mean annual catch of L. rohita in 1999 and L. calbasu in both 1998 and 1999 were much higher than their estimated maximum sustainable yield (MSY). Whereas the exploitation values for L. gonius were below the optimum level in 1998 and just at optimum in 1999. The stock of L. gonius is almost under optimum fishing level. Mean annual catch of L. gonius were lower or almost equal to its estimated MSY value in both the years. The Lc/L and M/K values also confirm the above conclusion for L. rohita, L. calbasu and L. gonius.
